Inaddition the <strong>T100</strong> has severalcomplementary modules which canbe used in a large number ofapplications.1. <strong>T100</strong> PowerIntroduction2. <strong>T100</strong> Power and HeatThe <strong>T100</strong> Power and Heat unit(<strong>T100</strong> PH) is the <strong>T100</strong> Powermodule combined with an exhaustgas heat exchanger. Thiscombination allows the <strong>T100</strong> toproduce combined heat and powerachieving very high overallefficiencies. The hot gases leaving themicroturbine are in this case used toproduce hot water. The overallefficiency of the microturbine will inthis way be highly improved.The <strong>Turbec</strong> <strong>T100</strong> Power (<strong>T100</strong> P)produces electrical power. It can beused in processes where the hotexhaust gases are used directly fordrying, cooling etc, or powerproduction only. The <strong>Turbec</strong> <strong>T100</strong> Puses a high speed generator toproduce electricity. The compressorand the turbine are placed on thesame shaft as the generator. Anexhaust gas recuperator is connectedto the microturbine to improve theelectrical efficiency. The scope ofsupply also includes an induced draft.3.

Control system1.1.1 Main components for <strong>T100</strong> PThe <strong>Turbec</strong> <strong>T100</strong> P consists of the following main parts:• Gas turbine engine• Electrical generator• Electrical system• Supervision and control systemGas turbine engineThe gas turbine is a single shaft engine. The maincomponents are:• Housing• Compressor• Recuperator• Combustion chamber• TurbineHousingThe electrical generator and the rotating components ofthe gas turbine are mounted on the same shaft. The partsare mounted in the same housing.CompressorThe <strong>Turbec</strong> <strong>T100</strong> uses a radial centrifugal compressor tocompress ambient air. The pressure ratio is about 4.5:1.The compressor is mounted on the same shaft as theturbine and the electrical generator.RecuperatorThe electrical efficiency of the gas turbine is increasedwith a recuperator. The recuperator is a gas-to-air heatexchanger attached to the microturbine. The heat isexchanged from the hot exhaust gases to the compressedair that is fed to the combustion chamber.Combustion chamberThe preheated compressed air is mixed with the fuel.During start up an electrical igniter in thecombustion chamber ignites the mixture.The combustion chamber is of lean pre-mixemission type, achieving exhaust gases withlow emissions of NO x, CO and unburned hydrocarbons.TurbineThe turbine drives the compressor and the generator.When the combustion gases leave the combustionchamber the temperature is approx. 950°C (1 742°F)and pressure is approximately 4.5 bar (65 psi). As thecombustion gases expand through the turbine thepressure decreases to nearly atmospheric pressure andthe temperature drops to approx. 650°C (1 202°F).Electrical generatorThe electric power is generated by a permanent magnetrotating at high speed. The generator rotor is suspendedby two bearings, one on each side of a permanent magnet.Further more, the generator acts as an electricstarter. The generator is water-cooled, and designed forhigh conversion efficiency.Electrical systemThe high frequency AC power from the generator isrectified and converted to the desired grid voltage and netfrequency. The AC power is rectified and converted tothe electrical grid frequency. A line filter and a transformerstabilizes and smoothes the AC output. Duringstart-up, power is taken from the grid and used forelectric start of the gas turbine.Supervision and control systemThe <strong>Turbec</strong> <strong>T100</strong> is controlled and supervised by anautomatic control system that resides at the PowerModule Controller (PMC) so the unit needs no personalattendance under normal operation. In case of griddistortion or system failure the system automatically shutsdown and the fault is logged by the PMC. The PMCcontrols and supervises the start-up, running and rollout.1. Generator2.

<strong>T100</strong> Power Module1. Generator2. Rectifier/Start converter3. DC bus4. Converter5. Line filter6. Transformer7. Main switchFor this purpose a set of variables are monitored throughsensors that measure:• Turbine outlet temperature• Power output• Oil and water temperature• VibrationsIn case of faults, the PMC executes one of the followingactions:• Normal stop• Emergency shut downThe fault is presented on the display at the operator´spanel to guide operating personell.1.1.2 Auxiliary systems for <strong>T100</strong> PThe auxiliary systems in the Power module are dividedinto the following systems:• Lubrication system• Cooling system• Air intake and ventilation system• Fuel gas system including fuel booster• Buffer air systemLubrication systemThe purpose of the system is to lubricate the squeezedfilm bearings on the rotor shaft. The system consists of aclosed piping system and an oil tank with an oil pumpplaced within the enclosure. A motor-driven pumpcirculates the lubrication oil. The lubrication oil circulatesfrom the bearings to an oil-to-air cooler and is cooledbelow 50°C (122°F). The PMC monitors oil pressure andoil temperature before and after the bearings to obtain areliable and continuous operation of the microturbineunit.Cooling systemThe generator is cooled with a separate closed coolingwater system placed within the enclosure.Air intake and ventilation systemA <strong>T100</strong> installed indoors draws ambient air from anoutdoor intake. As the air reaches the <strong>T100</strong>, the flow isdivided into two partial flows. The main flow acts ascombustion air in the microturbine. The secondary flowventilates the excess heat out from the Power module.An induced draft fan placed on the outside wall creates anegative pressure inside the enclosure, for safety reasonsand for cooling of the engine.The ventilation air enters the <strong>T100</strong> through an air duct.There are two air filters in the<strong>T100</strong> system,the pre filterand fine filter. The pre filter (optional supply) is placedclose to the outdoor intake of the air and the fine filter isplaced close to compressor within the enclosure forfiltering the combustion air.Fuel gas systemThe fuel gas system consists of a fuel control system and afuel booster. It is necessary to use a fuel booster to raisethe gas pressure when it is below 6 bar (g) (87 psig). Thefuel gas is taken into the fuel booster and discharged tothe fuel control system. In the combustion chamber, thefuel is mixed with preheated compressed air.Buffer air systemThe gas turbine compressor supplies the buffer air systemwith air to block the lubrication oil from entering the gasturbine engine and the generator. After the sealings, theair passes through an oil separator in which the oil mist isseparated from the air and collected in the lubrication oiltank.1.1.3 <strong>Technical</strong> data for <strong>T100</strong> PGeneral identificationType:<strong>Microturbine</strong>Manufacturer:<strong>Turbec</strong> Spa, ItalyModel:<strong>T100</strong> PApplication:Power generationUsage:Indoors (Option Outdoors)DimensionsWidth:900 mmHeight:1 810 mmLength:2 770 mmWeight:2 250 kgFuel:Natural gasAmbient inlet temperature: -25°C to 40°C (-13°F to 104°F)Ambient inlet humidity: < 100 %Surrounding air temperature: -10°C to 40°C (14°F to 104°F)Surrounding humidity: < 100 %Gas turbineCompressor type:CentrifugalTurbine type:RadialType of combustion chamber: Lean pre-mixNumber of combustionchamber: 1Pressure in combustionchamber:4.5 bar (a) (65 psia)Turbine inlet temperature: 950°C (1 742°F)Number of shaft: 1Nominal speed:70000 rpmConsumption of lubrication oil:

The<strong>T100</strong> unit follows these directives:Machinery Directive 98/37/ECNoise Directive 2000/14/ECElectromagnetic Compatiblity Directive 89/336/EEGwith amendments 92/31/EEG and 93/68/EEGLow Voltage Directive 73/23/EEC, 93/68/EECATEX 94/9/EC2.6 Maintenance conceptThe maintenance concept for the <strong>Turbec</strong> <strong>T100</strong> PH is thesame as for the <strong>T100</strong> P. For information about this, seesection 1.6 Maintenance concept.2.7 Operation of <strong>T100</strong> PHStartThe starting system is fully automatic and can be engagedby a push button on the local control panel or via theremote control system, an external Building ManagementSystem (BMS), a MODBUS communication orautomatically via an external weekly scheduler.The startup sequence includes starting, evacuation, ventilation andsynchronization to the grid.Normal start-up procedure will bring a cold <strong>T100</strong>microturbine into 80% load in 10 minutes, and 100%load in 20 minutes. During start up the generator operatesin motoring mode, using electrical power from thegrid. After 60 seconds of ventilation the combustor isignited, the generator speeds up and the power generationis started. The enclosure, the engine and the exhaustpipe are completely purged before ignition.Restart time after shutdown will be less than 5 minutes,provided that the engine is still warm. The <strong>T100</strong> isequipped with a function for automatic restart, activatedwhen the stop was caused by external disturbances. Ashort interuption or disturbance on the electrical grid willnot cause a <strong>T100</strong> stop. Instead it will disconnect from thegrid by opening the main contactor, keep the <strong>T100</strong>running supplying the <strong>T100</strong> auxiliaries and reconnectwhen the grid returns.Operating ModeThe <strong>T100</strong> microturbine operates mainly on standardspeed regulation, which results in a high efficiency in partload operation.Control SystemThe <strong>T100</strong> unit can be controlled in seven ways:• Locally by the Operators panel• Through hard-wired BMS<strong>Turbec</strong> Spa D14127-01 <strong>Technical</strong> description Ver 115
